Buying a home
Mortgage pre-approval NZ
Mortgage loan pre approval tells you how much a lender is prepared to lend before you find a house. Here’s how it works, what you need, and the conditions that catch people out.

Mortgage loan pre approval (also called home loan pre approval) is a lender’s conditional agreement to lend you up to a set amount, based on your income, expenses, debts and deposit. It usually lasts a few months, often around 90 days, and it isn’t a guarantee: the lender still has to approve the actual property before your loan is final.
What does mortgage loan pre approval actually mean?
When you apply, the lender checks your income, living costs, debts, credit history and deposit, then tells you the most it will lend and on what terms. That letter lets you shop with a real budget and make offers with more confidence.
Before you apply, check your credit score.
What it doesn’t do is approve a particular house. Once you’ve found one, the lender looks at the property itself: its value, its condition and sometimes its title. The loan only becomes unconditional after that step.
Pre-approval vs full approval
| Pre-approval | Full (unconditional) approval | |
|---|---|---|
| What’s assessed | You: income, expenses, debts, credit, deposit | You and the specific property |
| When | Before you house hunt | After your offer is accepted, or before an auction |
| Typical conditions | Valuation, building report, no change in your circumstances | Conditions satisfied, loan documents issued |
| Can it fall over? | Yes, if the property or your situation doesn’t stack up | Rarely, unless something material changes before settlement |
Found a house? Here’s what happens from pre-approval to settlement, step by step.
What you’ll need for home loan pre approval
- ID and proof of address.
- Income: recent payslips and an employment letter, or two years of financial statements if you’re self-employed.
- Bank statements, usually the last three months, showing your spending and savings.
- Deposit evidence, including a KiwiSaver balance and any gift letter.
- Debts: credit card limits, car loans, student loan, buy now pay later accounts.
Banks look at credit card limits, not balances, so closing cards you don’t use can lift what you’re able to borrow. See how credit cards and car loans affect borrowing.
What can stop a pre-approval turning into a loan
- The valuation comes in low, so your deposit is a smaller percentage than you planned.
- The property type is one the lender is cautious about, such as a small apartment, a leaky-era home or a cross-lease with alterations.
- Your situation changes: a new job still on probation, a new car loan, or a drop in income.
- The pre-approval expires before you buy, and the renewal is assessed under newer policy.
At auction there are no conditions, so you need the lender to sign off on the specific property before bidding. Read auction, tender or multi-offer for how that works.
Does applying hurt my credit score?
Each lender’s credit check is recorded as an enquiry. A few enquiries close together can make you look like you’re shopping around because you’ve been declined. Going through an adviser helps, because I can check which lender is likely to say yes before you apply.
Common questions
How long does mortgage pre-approval last in NZ?
It depends on the lender, but it’s often around three months. If it runs out before you buy, you can usually apply to renew it, and the lender will reassess you against its current policy.
Is pre-approval a guarantee I’ll get the loan?
No. It’s conditional. The lender still has to be happy with the property you choose and with your situation at the time you buy.
Can I get pre-approved with more than one bank?
You can, but each application adds a credit enquiry. It’s usually better to work out which lender suits you first and apply there.
How much will I be pre-approved for?
That depends on your income, expenses, debts and deposit. The borrowing calculator gives you a rough range before you apply.
What is the difference between home loan pre approval and getting a loan?
Home loan pre approval is the lender’s early, conditional yes based on you. The loan itself only goes ahead once the lender is also happy with the property. I work with 30+ lenders and help clients all over NZ, by phone or video.
Do I need home loans pre approval before making an offer?
It isn’t a legal requirement, but it is the sensible first step. Home loans pre approval gives you a real budget, and at an auction you can’t make your offer conditional on finance, so you need to be sure before you bid.
